Summary

As the US population ages, the prevalence of dementia is increasing, and Alzheimer's Disease (AD) is the most prevalent one. Solving the Alzheimer's Disease (AD) epidemic is likely to require preventive therapy beginning many years before symptoms are expected to be evident in at-risk individuals. AD is caused by the dysfunction, loss of synapses, and eventual neuronal death, which may occur up to 25 years before clinical symptoms appear. This study, based off of pre-clinical data, seeks to assess whether it is feasible to use memantine hydrochloride for the prevention of Alzheimer's Disease.

Conditions

  • Alzheimer Disease

Interventions

DRUG

Memantine Hydrochloride Tablets

The recommended starting dose of memantine hydrochloride/placebo is 5 mg once daily. The dose should be increased in 5 mg increments to 10 mg/day (5 mg twice daily), 15 mg/day (5 mg and 10 mg as separate doses), and 20 mg/day (10 mg twice daily). The minimum recommended interval between dose increases is one week. The dosage shown to be effective in controlled clinical trials is 20 mg/day.
